Domain Authority Checker - Free SEO Tools The Moz Domain Authority Checker is a free SEO tool that measures a website’s authority using Moz’s Domain Authority (DA) metric. It gives you a quick way to compare websites and evaluate the strength of their backlink profiles.
Domain Authority uses a scale from 0 to 100. Higher scores usually indicate stronger backlink profiles and greater ranking potential. Although Google does not use DA as a ranking factor, many SEO professionals rely on it for competitor research and link prospecting.
The checker can display several useful SEO metrics, including:
As a result, you can quickly compare websites and identify strong backlink opportunities.
Domain Authority (DA) and Ahrefs Domain Rating (DR) both estimate the strength of a website’s backlink profile. However, they use different databases and scoring methods. Therefore, it is normal to see different values for the same domain.
For a more complete SEO analysis, compare the results with an Ahrefs DR checker. Looking at both metrics provides a broader view of a website’s authority.
